What is the velocity of a penguin that swims 90 meters through water in 12 minutes

If the penguin has a consistent velocity the whole way, without anything accelerating him down. Then it is

90/12=7.5

So 7.5 meters/minute in the correct Si unit it would be

90/270=1/3 meters/second

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
